Pump Check Valve Requirements
NOTICE: In order to ensure maximum system reliability and water delivery, check valves must be installed in the drop pipe.
The first check valve must be installed at the pump (the 5-25 GPM (18-70 LPM) pumps have a built in check valve in the pump
discharge) and additional check valves should be installed every 100 ft. (30 m.) of vertical pipe after the pump. (See the pump
owner's manual for additional information.)
